Introduction: Carbon emission cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Therefore, reducing carbon emission is important because it mitigates the effects of global climate change, improves public health and maintains biodiversity. In carbon sequestration process atmospheric carbon is taken up by trees, grasses and plants through photosynthesis. Aim: Analyse the carbon emissions and estimate the carbon sequestration. Methodology: The study was conducted at Golihalli and Bidi village of Belagavi district, Karnataka in India to measure the carbon emission level through Air Quality Monitor and CO meter for one year. The carbon sequestration was assessed by non-destructive method. Results: An annual mean concentration of CO2 in Golihalli village was 924.33 ppm while in Bidi village 929.9 ppm and also the mean concentration of CO was 25.7 ppm in Golihalli village whereas 25.8 ppm in Bidi village. The mean concentration of PM2.5 was 57.8 μm3 and PM10 was 107.5 μm3 in Golihalli village however PM2.5 was 57.9 μm3 and PM10 was 108 μm3 in Bidi village. During the observation period, the maximum carbon emission concentration was measured in summer season and the minimum in rainy season. The largest value of carbon sequestration was seen in Tamarindus indica (530.22 gm) in Bidi village and Azdirachta indica (519.77 gm) in Golihalli       village. Conclusion: The carbon emission concentration was exceeding the safe level in both villages because of rural people’s day-today activities and vehicular pollution. The trees with higher age and DBH have more carbon sequestration which could help in mitigate the effects of carbon emitted in the village.

Proper waste management is a major concern of public health. It is necessary to create positive behavioral changes toward waste management among the public to control diseases. Objectives were to determine the attitude toward solid waste management among the households of Hubli - Dharwad city in Karnataka, India. A community based cross sectional study was conducted in 67 wards of Hubli- Dharwad city located in the Dharwad district of Karnataka state from January 2021 to December 2021. A total of 400 households were studied and multistage sampling was done. Data was collected by direct interview using a pre-questionnaire and  analyzed using SPSS software.  The participants responsible for waste management in the household were women. Out of the 400 participants, 83%, 11% and 6% were Hindus, Muslims and Christians respectively. The majority of them (82%) had an educational qualification of high school and were housewives. About 47% of the study population belongs to the upper middle class. Their major sources of information about solid waste management were Self Help Groups (SHGs). In the study, 93.8% of the studied population had above average attitudes and 6.2% had below average attitudes toward household waste management. Almost 70% had the belief that the government is not doing anything to fix the garbage problem. About 97%, 88.6% and 92% were willing to do composting, segregation and recycling of waste respectively. . Continuous awareness programs have to be conducted on safe waste disposal and efforts should be made to sustain the supervision of household waste management.
